I recently picked up another project car, anyone want to chime in on causes of this amount of sludge. 2003 Tdi Vw with 148k miles, turbo failed due to clogged supply line go figure! Previouse owner swears he did 10k oil change full synth. The car was only driven in the summer, parked each winter. No information on brand or diesel specific oil, or if it was changed before parking for the winter.

Gentlemen, we can rebuild it. We have the technology. We have the capability to rebuild the world's first super-sludged engine. Matt will be that man. Better than it was before. Better, stronger, faster.

Ten years of wrong oil, no soot suspension, and long intervals of sitting in the cold for the collection of goo at the bottom of the pan? I'm a believer.If you rebuild, '03s had a poor alternator history. Be advised.

You will need to spends massive amounts of money getting that engine back up and running reliably.

The only situation i can see when the previous owner was telling the about the oil changes is if there was significant diesel contamination of the oil which can cause the oil to turn into a thick black vaseline like substance.

But i have only ever seen it in dpf equipped vehicles that have had repeated failed regens and the oil and filter was not changed at the same time as a forced regen.

Only a small number of Citreon and Peugeot vehicles had dpf back in 03 and i don't think many would have got to the US as they were hardly sold in the UK.
